Absolute Addresses: When data is accessed by absolute address, place the absolute address value
in a table in memory beforehand. The absolute address value is transferred to a register using the
method whereby immediate data is loaded when an instruction is executed, and the data is
accessed using the register indirect addressing mode.

16-Bit/32-Bit Displacement: When data is accessed using the 16- or 32-bit displacement
addressing mode, the displacement value is placed in a table in memory beforehand. Using the
method whereby immediate data is loaded when an instruction is executed, this value is
transferred to a register and the data is accessed using index register indirect addressing mode.
